Question

The cost of a trip is $3.15 plus $0.95 for every kilometre that you ride on a bus. Which of the following expressions gives the cost of a trip of k kilometres?

Answer 1

.95k+3.15

Explanation:

To write an expression you need a variable (k). I look at the directions and I see that the length of the trip is 'k' kilometers. So I pay the flat fee of 3.15 ONE TIME. Then I pay $0.95 for every kilometer I go, so the expression is

-> .95k+3.15

Answer 2

Answer: 0.95k + 3.15

Explanation:

0.95k is because each of k kilometers costs $0.95. + 3.15 is because it costs 3.15 as a flat rate regardless of distance
